Hitachi – SU3900SE
Schottky field emission SEM with variable pressure and extra‑large specimen chamber.
The SU3900SE specimen stage has been redesigned to allow operators to observe heavy samples weighing up to 5 kg.
As the largest stage in Hitachi High-Tech’s scanning electron microscope lineup, it can accommodate large specimens up to 300 mm in diameter and 130 mm in height, approximately 1.5 times larger than its SU5000 predecessor.
This minimizes the need for additional sample preparation steps such as cutting, improving overall process efficiency, while a motorized 5‑axis stage (X, Y, Z, tilt, and rotation) provides precise specimen control.
These new instruments also feature a camera navigation function that stitches separate images into a full‑sample view, helping operators identify regions of interest on large specimens and enhancing usability.
In line with Hitachi High-Tech’s commitment to a sustainable society, the environmentally friendly design cuts CO₂ emissions by reducing power consumption to 2 kVA, about 50% lower than existing FE‑SEM models, while maintaining high performance.
Features and variations
- Wide‑area observation of large/heavy specimens.
- Simple large‑area navigation using optical camera images.
- Reduced operator workload when acquiring large volumes of data.
